Experimental Study of a New PVC Foam Insulation System for Liquid-Hydrogen-Liquid-Oxygen Space Vehicles

Abstract

This paper discusses the development of a rigid external foam insulation for liquid-hydrogen-liquid-oxygen space vehicles and is a continuation of the work, first discussed in 1966 [1], dealing with the use of Klegecell G 300,* a PVC closed-cell foam. This foam does not require a vapor barrier for protection against cryopumping.
